UNASSIGNED: A lack of patient safety research hampers capacity to improve safety in healthcare.Ultrasound is often considered \'safe\' as it does not use ionising radiation, a simplistic view of patient safety. Understanding sonographers\' actions towards patient safety is crucial; however, self-reported measures cannot always predict behaviour. This study is part of a PhD exploring patient safety in medical diagnostic ultrasound. The aim of this paper is to explore sonographers\' responses to the patient safety concerns identified in Part one of this study. The ultimate aim of the study is to inform the final phase of the doctoral study which will consider the next steps in improving the quality and safety of healthcare experienced by patients.
UNASSIGNED: A qualitative study using semi-structured, one-on-one interviews. The Theory of Planned Behaviour (TPB) explained how sonographers respond to perceived patient safety risks in practice.
UNASSIGNED: Thirty-one sonographers were interviewed. Based on the seven themes identified in Part one of the study, results showed that incongruences exist between identifying patient safety risks and the actions taken in practice to manage these risks.
UNASSIGNED: The TPB showed that behavioural, normative and control beliefs impact sonographers\' responses to perceived patient safety risks in practice and can lead to risk avoidance. Lack of regulation in ultrasound creates a challenge in dealing with Fitness to Practice issues. Collective actions are required to support sonographers in taking appropriate actions to enhance patient safety from multiple stakeholders including accreditation bodies, regulatory authorities, educational institutions and employers.

Our study aimed to determine the publication rates of podium presentations from the 2017 and 2018 Society of Gynecologic Oncology (SGO) Annual Meetings; and to examine rates and predictors of oral presentations that resulted in publication.
We reviewed podium presentations given at the 2017 and 2018 SGO Annual Meetings. Abstracts were evaluated for publication from January 1, 2017 to March 30, 2020 and January 1, 2018 to June 30, 2021, respectively, to allow for a 3 year period of publication.
In 2017 and 2018, 43 of 75 (57.3%) and 47 of 83 (56.6%) podium presentations were published within 3 years, respectively. No significant difference was found between the mean time to publication within 3 years (13.0 months vs 14.1 months for 2017 and 2018, respectively; p=0.96). Similarly, the mean difference of journal impact factors between both years did not reach significance (6.57 and 10.7 for 2017 and 2018, respectively; p=0.09). The median impact factor (IF) was 4.54 (range: 40.3) and 4.62 (range: 70.7) in 2017 and 2018, respectively. Of the presentations published, 53.4% (2017) and 38.3% (2018) appeared in the journal Gynecologic Oncology. Significant positive correlations for the likelihood of publication were determined among the following: funding status (r=0.93) including funding involving National Institutes for Health (r=0.91) or pharmaceutical (r=0.95), clinical trial study design (r=0.94), and pre-clinical research (r=0.95) (all p<0.005).
At the 2017 and 2018 SGO Annual Meetings 57% of podium presentations were published in a peer-reviewed journal within 3 years. Publication in peer-reviewed journals is crucial for timely distribution of clinical information to the medical community.

The objective of this study was to describe family visitation policies, facilities, and support in Australia and New Zealand (ANZ) intensive care units (ICUs).
A survey was distributed to all Australian and New Zealand ICUs reporting to the Australian and New Zealand Intensive Care Society Centre for Outcomes and Resources Evaluation Critical Care Resources (CCR) Registry in 2018. Data were obtained from the survey and from data reported to the CCR Registry. For this study, open visiting (OV) was defined as allowing visitors for more than 14 h per day.
This study included all Australian and New Zealand ICUs reporting to CCR in 2018.
The main outcome measures were family access to the ICU and visiting hours, characteristics of the ICU waiting area, and information provided to and collected from the relatives.
Fifty-six percent (95/170) of ICUs contributing to CCR responded, representing 44% of ANZ ICUs and a range of rural, metropolitan, tertiary, and private ICUs. Visiting hours ranged from 1.5 to 24 h per day, with 68 (72%) respondent ICUs reporting an OV policy, of which 64 (67%) ICUs were open to visitors 24 h a day. A waiting room was part of the ICU for 77 (81%) respondent ICUs, 74 (78%) reported a separate dedicated room for family meetings, and 83 (87%) reported available social worker services. Most ICUs reported facilities for sleeping within or near the hospital. An information booklet was provided by 64 (67%) ICUs. Only six (6%) ICUs required personal protective equipment for all visitors, and 76 (80%) required personal protective equipment for patients with airborne precautions.
In 2018, the majority of ANZ ICUs reported liberal visiting policies, with substantial facilities and family support.

BACKGROUND: For all the amides detected in the interstellar medium (ISM), the corresponding nitriles or isonitriles have also been detected in the ISM, some of which have relatively high abundances. Among the abundant nitriles for which the corresponding amide has not yet been detected is cyanoacetylene (HCCCN), whose amide counterpart is propiolamide (HCCC(O)NH2).
OBJECTIVE: With the aim of supporting searches for this amide in the ISM, we provide a complete rotational study of propiolamide from 6 GHz to 440 GHz.
METHODS: Time-domain Fourier transform microwave (FTMW) spectroscopy under supersonic expansion conditions between 6 GHz and 18 GHz was used to accurately measure and analyze ground-state rotational transitions with resolved hyperfine structure arising from nuclear quadrupole coupling interactions of the 14N nucleus. We combined this technique with the frequency-domain room-temperature millimeter wave and submillimeter wave spectroscopies from 75 GHz to 440 GHz in order to record and assign the rotational spectra in the ground state and in the low-lying excited vibrational states. We used the ReMoCA spectral line survey performed with the Atacama Large Millimeter/submillimeter Array toward the star-forming region Sgr B2(N) to search for propiolamide.
RESULTS: We identified and measured more than 5500 distinct frequency lines of propiolamide in the laboratory. These lines were fitted using an effective semi-rigid rotor Hamiltonian with nuclear quadrupole coupling interactions taken into consideration. We obtained accurate sets of spectroscopic parameters for the ground state and the three low-lying excited vibrational states. We report the nondetection of propiolamide toward the hot cores Sgr B2(N1S) and Sgr B2(N2). We find that propiolamide is at least 50 and 13 times less abundant than acetamide in Sgr B2(N1S) and Sgr B2(N2), respectively, indicating that the abundance difference between both amides is more pronounced by at least a factor of 8 and 2, respectively, than for their corresponding nitriles.
CONCLUSIONS: Although propiolamide has yet to be included in astrochemical modeling networks, the observed upper limit to the ratio of propiolamide to acetamide seems consistent with the ratios of related species as determined from past simulations. The comprehensive spectroscopic data presented in this paper will aid future astronomical searches.

UNASSIGNED: Report a series of cases in which patients have concomitant superior semicircular canal dehiscence (SSCD) and a dehiscent tegmen tympani with Dural contact to the malleus head (DCMH).
UNASSIGNED: An analysis of radiologic and audiologic data in 4 patients who presented with SSCD and DCMH at a tertiary care institution. A pertinent literature review was performed.
UNASSIGNED: Four patients (5 ears) had SSCD and DCMH. In 3 patients with unilateral DCMH, the mean maximum air-bone gap was 15 dB in the ear with DCMH compared to 50 dB in the ear without DCMH. Of the 5 ears with DCMH, the mean air conduction threshold at 250 Hz was 17 dB compared to 42 dB in the 3 ears without DCMH.
UNASSIGNED: We report the findings of DCMH in a series of 4 patients with bilateral SSCD. This limited series suggests that ears with SSCD and DCMH have less of an air-bone gap than would be expected, as 1 would expect an additive effect of DCMH and SSCD on the air-bone gap.

UNASSIGNED: We explored the auditory and anatomical success of grafting when the cartilage perichondrium (CP) was prepared using two different methods.
UNASSIGNED: Patients with subtotal or total perforation underwent tympanoplasty with a CP graft. A V-shaped groove for the handle of the malleus was prepared for CP grafts in patients in group 1. Patients in group 2 did not have a groove on the graft. The anatomical success of the graft was evaluated as success, partial success, or failure. Results of auditory evaluations were compared between the two groups.
UNASSIGNED: A total of 195 patients were included in the study. The total CP graft integration rate was 96% for both groups. Significant changes were detected in all hearing criteria evaluated 12 months after surgery compared to the preoperative period (P < .05). There were no significant differences between the groups in terms of the relationship between graft technique and postoperative hearing results. However, rates of partial success were significantly higher for group 1 than group 2 (P = .033).
UNASSIGNED: Cartilage slice support offers an extremely reliable method for reconstruction of tympanic membrane in cases of high-risk perforation. Partial failures are rare, but when they occur, they most often involved anterior graft medialization. When a piece of cartilage is removed at the malleus interface there may be a higher rate of partial failure.

UNASSIGNED: We report obstructing laryngeal manifestations of Crohn\'s disease in a toddler with very early onset-IBD (VEO-IBD) who required tracheotomy tube placement at 27 months of age for relief of recalcitrant airway obstruction unresponsive to maximal medical therapy. We review the literature for the frequency of extra-intestinal laryngeal manifestations of Crohn\'s disease in adults and children.
UNASSIGNED: Case report and literature review of laryngeal manifestations of Crohn\'s disease.
UNASSIGNED: Laryngeal involvement of Crohn\'s disease is very rare with only 14 other cases reported. Most cases appear in adults, with the supraglottis most commonly affected. This case marks the youngest report and only the second report of a patient requiring a tracheotomy for supraglottic obstruction when intensive medical management, including use of steroids and biologics, failed to relieve obstructing laryngeal inflammation. Despite ongoing Crohn\'s disease, laryngeal manifestations improved permitting decannulation the following year.
UNASSIGNED: Laryngeal manifestations of Crohn\'s disease are rare and usually affect adults. Most cases are managed with medical therapy, however surgical excision of obstructing lesions or tracheotomy placement is sometimes required for temporary relief of airway obstruction.

UNASSIGNED: An indeterminate thyroid nodule fine-needle aspiration (FNA) presents a unique dilemma. We evaluated our institution\'s experience with Bethesda III thyroid nodules, including the risk of malignancy (ROM) of these nodules removed for diagnostic lobectomy and radiologic and clinical risk factors for malignancy.
UNASSIGNED: Retrospective chart review.
UNASSIGNED: San Antonio Military Medical Center (SAMMC; 483 bed Military Treatment Facility and Level 1 Trauma Center).
UNASSIGNED: We identified all patients with a Bethesda III thyroid FNA at our institution from 2010 to 2018 and determined which nodules were removed. The final histological diagnosis was recorded. Whether or not age, gender, body mass index (BMI), race, nodule size, margin regularity, rate of nodule growth, vascularity, internal calcifications, family history of thyroid cancer, personal history of radiation, and history of repeated AUS/FLUS on FNA had a significant impact on malignancy risk was evaluated with chi square and rank sum Wilcoxon tests.
UNASSIGNED: 492 patients had 1 or more AUS result. 52% (258/492) underwent repeat FNA. This resulted in Bethesda II or III in 90% (232/258). In 10% (26/258), the repeat FNA resulted in a higher Bethesda grade. 183 lobectomies were performed on the side containing an AUS nodule. The malignancy percentage was 38.3% (70/183). Age less than 30 was the only variable showing statistical significance for increased risk of malignancy (P = .04).
UNASSIGNED: The ROM of nodules characterized as AUS/FLUS on FNA may be higher than expected. Age may be a better predictor of malignancy than repeat FNA.

UNASSIGNED: Surgery on the ossicular chain may impact its underlying mechanical properties. This study aims to investigate comparative differences in frequency-specific hearing outcomes for ossiculoplasty versus stapedotomy.
UNASSIGNED: A retrospective chart review was conducted on subjects who underwent ossiculoplasty with partial ossicular replacement prosthesis (PORP) or laser stapedotomy with self-crimping nitinol/fluoroplastic piston, and achieved closure of postoperative pure tone average air-bone gap (PTA-ABG) ≤ 15 dB. 45 PORP and 38 stapedotomy cases were included, with mean length of follow-up of 7.6 months.
UNASSIGNED: The mean change in PTA-ABG was similar for the 2 procedures (-17.9 dB vs -18.1 dB, P = .98). Postoperative ABG closure for stapedotomy was superior at 1000 Hz (8.9 dB vs 13.9 dB, P = .0003) and 4000 Hz (11.8 dB vs 18.0 dB, P = .0073). Both procedures also had improved postoperative bone conduction (BC) thresholds at nearly all frequencies, but there was no statistical difference in the change in BC at any particular frequency between the 2 procedures.
UNASSIGNED: Both procedures achieved a similar mean change in PTA-ABG. Stapedotomy was superior to PORP at ABG closure at 1000 Hz and at 4000 Hz, with 1000 Hz the most discrepant. The exact mechanism responsible for these changes is unclear, but the specific frequencies affected suggest that differences in each procedure\'s respective impact on the native resonant frequency and mass load of the system could be implicated.
